Planet earth is generally thought of a composed of the atmosphere, the hydrosphere, the lithosphere and the biosphere. The geosphere is often used to mean the same thing as lithosphere - rocks and stones. If this is how you are using the word, then the geosphere consists of the crust, the mantle and the core.

Transfer speed â USB 3.0 adds a new transfer type called SuperSpeed or SS, 5 Gbit/s (electrically, it is more similar to PCI Express 2.0 and SATA than USB 2.0) Increased bandwidth â instead of one-way communication, USB 3.0 uses two unidirectional data paths: one to receive data and the other to transmit.
The single biggest factor in USB drive performance is whether it contains one of two types of memory: SLC (single-level cell) or MLC (multilevel cell). SLC stores one bit, and MLC stores two bits of data in each memory cell.
